Question #43442

A gas sample occupies a volume of 1000 mL at 40 degrees celsius and a pressure of 760 torr. If , at the same temperature, the pressure were decreased to 380 torr, what volume would result?

a) 500 mL

b) 1000 mL

c) 1500 mL

d) 2000 mL

a) 500 mL

b) 1000 mL

c) 1500 mL

d) 2000 mL

Expert's answer

According to the Boyle's law,

P

Hence, we can calculate the gas volume:

V

So, the correct option is (d): 2000 mL

P

_{1}V_{1}= P_{2}V_{2}Hence, we can calculate the gas volume:

V

_{2}= P_{1}V_{1}/P_{2}= (760 torr * 1000 mL) / 380 torr = 2000 mLSo, the correct option is (d): 2000 mL
